The Fill tool allows you to create fill surfaces between a numbers of boundary
segments. These may be planar or non-planar, but there should not be a large gap
between the consecutive boundary segments. Before creating a fill surface, draw the
boundary curves. Next, choose Fill button from the Surface toolbar.
Next, you are required to select the boundary segments. You need to make sure that
while selecting the boundary segments, the sequence of selection should be such that a

Chapter 6: ASSEMBLYDESIGN.
6.1 INTRODUCTION:
This module is responsible for assembling the parts previously produced in Part Design,
and it is most important for those who work in the field of machinery design or design
in general, because it is the one who shows the inter-relationships between the parts of
the machine or any mechanical establishment. Assembly modelling is the process of
creating designs that consist of two or more components assembled together at their
respective work positions. The components are brought together and assembled in
Assembly Design workbench by applying suitable parametric assembly
Constraints to them.
6.2 Types of Assembly Design Approach:
In CATIA you can create assembly models by adopting two types of approaches. The
first design approach is the bottom-up approach, and the second one is the top-down
approach. Both these design approaches are discussed below.
6.2.1 Bottom-up Assembly:
The bottom-up assembly is the most preferred approach for creating assembly models.
In this of approach, the components are created in the Part Design workbench file. Then
the product file is started and all the previously created components are inserted and
placed in it using the tools provided in the Assembly Design workbench. After inserting
each component, constraints are applied to position them properly in the 3D space with
respect to other components.
6.2.2 Top-down Assembly:
In the top-down assembly design approach, components are created inside the
Assembly Design workbench. Therefore, there is no need to create separate part files
of the components. This design approach is completely different from the bottom-up
design approach. Here you have to start the product file first and then, one by one, create
all components. Note that even though the components are created inside the product
file, they are saved as individual part files and can be opened separately later.
6.3 Product Structure Tools Toolbar:
This first task shows how to insert new component, new part and existing component.
Fig 6.1 product structure tools toolbar
27. 27
6.3.1 Inserting a New Component:
This task will show you how to insert a component into an existing assembly. This
command lets you: create an instance from the reference chosen component use a
context-specific representation inside it.
6.3.2 Inserting a New Part:
This task will show you how to insert a part in an existing assembly.
1. In the specification tree, select ManagingComponents01 and click the New Part
icon. If geometry exists in the assembly, the New Part: Origin Point dialog box is
displayed, proposing two options to locate the part:
Click Yes to locate the part origin point on a selected point, on another
component for example.
Click No to define the origin point of a component according to the origin
point of the parent component
2. For the purposes of this task, click No to locate the part origin according to the
Product1 origin point.
6.3.3 Inserting Existing Components:
This task will show you how to import one or more components into an existing
assembly.You can specify the order in which the files will be imported when you
select the files in the Insert an Existing Component dialog box.
6.3.4 Replacing a Component:
This task consists in replacing a component.
Using the Replacement Component command means replacing one component with
another.
6.4 Constraint toolbar:
Constraints can either be dimensional or geometrical. Dimensional constraints are used
to constrain the length of an element, the radius or diameter of an arc or circle, and the
distance or angle between elements. Geometrical constraints are used to constrain the
orientation of one element relative to another. Other common geometrical constraints
include parallel, tangent, coincident, concentric, etc... Reading from left to right:
Fig 6.2 Constraint toolbar
28. 28
6.4.1 Creating a Coincidence Constraint:
Coincidence type constraints are used to align elements. Depending on the selected
elements, you may obtain concentricity, coaxiality or coplanarity. This task consists in
applying a constraint between two faces.
6.4.2 Creating a Contact Constraint:
Contact type constraints can be created between two planes or faces. The common area
between the two planes can be a plane (plane contact), a line (line contact) or a point
(point contact).
6.4.3 Creating an Angle Constraint:
Angle type constraints fall into three categories:
1. Angle, 2.Parallelism (angle value equals zero),
3. Perpendicularity (angle value equals 90º)
When setting an angle constraint, you will have to define an angle value. Note that this
angle value must not exceed 90o.The tolerance i.e. the smallest angle that can be used
to differentiate two elements is set at 10 -6 radians.
6.4.4 Fixing a Component:
Fixing a component means preventing this component from moving from its parent
component during the update operation. Note that it does not mean fixing its position
according to the geometrical origin of the assembly. To fix the component location
according to the geometrical origin of the assembly, check Fix in space in the constraint
Properties dialog box.
6.4.5 Fixing Components Together:
The Fix Together command attaches selected elements together. You can select as
many components as you wish, but they must belong to the active component. This task
consists in fixing two components together.
Using the Auto constraint Command
The Auto constraint mode allows you to create the first possible constraint as specified
in the priority list. This task consists in using the Auto constraint command to create
two constraints.
